In the autumn of 1885 Dr. Grinnell, J. B. Monroe, and I made a trip up Swift Current River, and discovered and roughly measured the big glacier at the head of its middle fork, Dr. Grinnell killing a big ram on the ice while we were traversing it and avoiding its deep crevasses. That evening Monroe and I named the glacier in honor of Dr. Grinnell, and also named the mountain to the north of it after him. On the following day we were joined by Lieutenant--now Major--J. H. Beacom, Third Infantry, and he gave my Indian name, Apikuni, to the high mountain between Swift Current and the South Fork of Kennedy Creek. Upon our return to Upper St. Mary's Lake, Dr. Grinnell named Little Chief Mountain, Monroe gave Citadel Mountain its name, and I named Yellow Fish, Goat, Going-to-the-Sun, and Four Bears Mountains. Yellow Fish (O-to-ko´-mi) was an Indian who often hunted with us, and Four Bears (Nis-su´-kyai-yo) was the Blackfeet camp crier, and a most amusing man. It was in 1886, I believe, that we three, and my old-time friend, William Jackson, one-time scout for General Custer and General Miles, cut a trail to the head of the St. Mary's Valley and discovered the great sheet of ice which we named the Blackfeet Glacier. We at the same time named Gun-Sight Pass, and named the peak just west of the glacier, Mount Jackson. It should be Sik-si-kai´-kwan (Blackfeet Man), Jackson's Indian name. He was a grandson of Hugh Monroe, a real plainsman, and one of the bravest men I ever knew. [Illustration: GOING-TO-THE-SUN MOUNTAIN] Going-to-the-Sun has been climbed this day, and a flag has been planted upon its summit, by Paul E. Walker, Esq., of Topeka, Kansas. Owing to a high cliff upon its upper shoulder, the mountain has always been considered unclimbable. But after long search, and with no little risk, Mr. Walker finally worked out a way up the wall, and out upon the extreme crest, and was undoubtedly the first man, white or red, ever to stand there. He reports that a magnificent view of the mountains and plains is to be had from the great height. _August 12._ We have more real meat in camp. Yesterday Black Bull went up under the north point of Flat Top Mountain, which is on the Indian Reservation, and killed two fat young rams. I went fishing, and in the first pool of the river below the upper lake, caught several two- and three-pound cutthroat trout. We had a great feast in the evening--roast bighorn ribs, broiled trout, a quantity of blueberries, and so on.
